Current draw for TPMS repeater? Oops.

[dbledan]

I left my TPMS repeater wired up when I went to store the trailer. I am not sure how much current they draw but worried about killing the battery. Everything else is disconnected so no other draw.

It has been a week since I stored it now. I plan to go remove it but I cannot get to it for a few days. I was wondering if I should pull the battery to recharge/restore it or if it is just a drop in the bucket. I have the TST507 repeater. I cannot find the spec for it. Hoping Mike

Hopefully Mike will chime in with a detailed answer. Thou I expect that you should be fine for a week.
FWIW, I connected mine to the downstream side of my battery disconnect. I use the red light on the repeater to remind me to shut the power down.

Yea I just quick wired to the battery. I plan to wire to the disconnect but so easy to tie it to the posts and leave it all in the battery box. I got lazy because it was raining and cold when I needed to hook it up.

I have mine new in box here st home. There is nothing in the manual stating current draw. I can tell you there is only a 2A inline fuse in the system so the draw must be very little.

If you really need the hard numbers when I get home tomorrow I can run a multimeter on the trucks battery and get you the real number.

I went and got it and put the battery on a trickle charger so I am good now. It was not dead after a week and a half so not too bad. I can check the draw at home.

I put a plug on mine for that reason. My batteries are almost always connected to shore power and I didn’t see a need to run the repeater unless I was moving and I could then just plug it in.
